Litigation holds preserve email from being tampered with until the litigation hold expires or is removed. Native and mobile apps provide intuitive interfaces that simplify search to ensure messages are found easily, even when email services are unavailable.

Business Continuity

Barracuda Email Security ensures that email can still be delivered even during email server failures or loss of connectivity. In the event of email server disruptions, email can be spooled in the Cloud Protection Layer for up to 96 hours. If delivery to the primary destination fails, an alternate destination can be specified for delivery.

During email server outages, the email for all mail servers is visible through the Cloud Protection Layer. From the message log, you can see the status of all spooled emails, and whether mail has been redelivered.

Benefits:

Comprehensive and 100% Cloud-Based Email Security and Archiving for all Organizations

Barracuda's Essentials for Email Security protects your organization with comprehensive, scalable and affordable multi-layer security and archiving whether you use on-premises email like Microsoft Exchange, or a cloud-based productivity suite like Google Apps for Work or Education.

Email continues to be a primary communication channel and thus is also one of the most frequently exploited threat vectors. Email-borne data breaches, data leaks, business disruptions as well as compliance and litigation searches cost money and reputation.

In addition to spam-based attacks, email threats have evolved to highly sophisticated phishing campaigns, targeted zero-hour attacks and data theft aimed at exploiting risky user behavior. With 91% of hacks starting with a targeted email attack, organizations need to protect their users, data and assets. If you are running Exchange on-premises or it is hosted in the cloud, you also have to deal with the added challenge of email and business continuity.

Compliance and preservation of email is now a key requirement for many organizations, and the penalties for not meeting business and governmental regulations can be severe.

Barracuda Essentials for Email Security combines several layers of protection for inbound and outbound email to secure against the most advanced email borne attacks, email spooling to ensure business continuity, and archiving for organizations to meet demanding compliance and preservation requirements and address eDiscovery requests effectively and easily.

The Barracuda Essentials for Email Security quickly filters every email before it hits your mail server to protect against inbound malware, spam, phishing and Denial of Service attacks. Features include sender spoof protection, domain name validation and anti-fraud intelligence.

The service is powered by Barracuda Central, our global 24x7 threat operations center that constantly monitors the Internet for new email-borne threats across all attack vectors. The service is continuously updated with the latest threat definitions intelligence and software updates which means zero maintenance cost to you.

Our scalable cloud and prioritized filtering technology ensures that you get the best possible level of protection without adding significant delays to the time it takes to receive emails – even during peak load times during the day.

Key Features: Barracuda Central

Protect against Targeted Attacks and Advanced Persistent Threats

Our Advanced Threat Detection goes beyond inbound email filtering to provide comprehensive protection from targeted attacks that may contain malicious links and attachments. We utilize a full system emulation sandbox to prevent suspicious URLs and files from reaching your users.

Barracuda Link Protection detects malicious and malformed URLs at click-time, and redirects them to our sandbox so users are protected from potential malware and ransomware.

Available Advanced Threat Detection opens suspicious attachments in our sandbox and detonates them in real-time to protect users from these highly-effective, socially-engineered attacks.

Outbound filtering keeps sensitive data from leaving your organization while simultaneously ensuring that legitimate emails are delivered. At the same time, outbound filtering also blocks outbound spam and viruses, preventing your employees or other infected clients from inadvertently sending malicious email, as well as keeping your mail server IP addresses and domains from being listed on spam block lists.

Employees can inadvertently allow their email to be used for botnet spam. The outbound filter stops outbound spam and viruses.

Administrators can also create and enforce content policies to prevent sensitive data such as credit card numbers, social security numbers, HIPAA data, customer lists and other private information from being sent by email. Policies can automatically encrypt, quarantine or even block certain outbound emails based on their content, sender or recipient.

Key Features: Outbound Filtering

Secure Your Communication with Email Encryption and Spooling

Your emails can travel through many different servers before they reach the intended mailbox. The Barracuda Essentials for Email Security secures your mail by encrypting it during transport to the Barracuda Message Center, encrypting it at rest for storage in the cloud, and providing secure retrieval by your recipients through HTTPS Web access. Data in-motion is secured via Transport Layer Security (TLS), and data at-rest is secured via AES 256-bit encryption.

If you are sending a sensitive email, you can manually mark it for encryption. However, you can also create a policy to automatically encrypt emails based on their sender, content and other criteria. Encryption policies ensure that your organization complies with regulations designed to protect customer data, such as HIPAA.

All of the encryption in the world is meaningless if your emails don’t get delivered. In the event of a disruption in your mail server, email can be spooled on Barracuda’s Cloud Protection Layer for up to 96 hours. An alternate destination can also be specified for delivery if delivery to the primary destination fails.

Preserve Emails for Retention and Compliance

Compliance is now a key requirement for many organizations, and the penalties for not meeting business and governmental regulations can be severe. These must be implemented in all areas across the organization to demonstrate and ensure that the business is operating in a compliant manner and to minimize ongoing legal risk. Barracuda Cloud Archiving Service takes a policy-based approach to meeting this need, automating and enforcing both the retention and the deletion of email as required. With Barracuda Cloud Archiving Service, you save only what is needed and only for the time that it needs to be saved, and you can be confident that your day?to?day email operations meet government and regulatory compliance standards. In response to regulatory audits, you can demonstrate adherence to retention and defensible deletion policies.

Features:

Advanced Threat Detection

Barracuda's Advanced Threat Detection (ATP) combines behavioral, heuristic, and sandboxing technologies to protect against zero hour and targeted attacks. ATP automatically scans email attachments in real-time; suspicious attachments are detonated in a sandbox environment to observe behavior. In addition to blocking the attachment, the results are integrated into the Barracuda Real Time System providing protection for all other customers.

Malware Protection

Link Protection

Anti-phishing also includes Link Protection. A popular method that attackers use to deliver malware relies on URLs that contain malicious code, which can be invisibly downloaded and can trigger a much larger attack. Link Protection automatically rewrites these URLs so that the Barracuda Essentials for Email Security can sandbox the request at click time to block malicious links.

Typosquatting Protection

More sophisticated attackers make clever modifications to URLs so they look genuine, but are not. The most common technique is omitting letters or using convincing “typos” that even users who check URLs before clicking often miss. Barracuda’s Link Protection includes typosquatting detection, which automatically identifies and redirects these URLs to our sandbox at click time to block malicious activity.

Integrated End-User Security Training

By integrating end-user security education and training exercises into the Barracuda Email Security technology, users that click on malicious links are taken to a landing page where they can take training exercises to understand what they did wrong and how to avoid repeating this mistake moving forward. The exercises run about five minutes and take the user through a course to understand who is behind these attacks, what to look for, and a test to ensure they can apply what they’ve just learned.

Anti-Spam Protection

With a long-standing heritage in spam protection, Barracuda Networks remains the leader in identifying and blocking spam. A comprehensive set of security layers ensures that organizations remain productive in the face of evolving threats.

The Barracuda Essentials for Email Security leverages Barracuda Central to identify email from known spammers and determine whether domains embedded in email lead to known spam or malware domains. It leverages many of the same industry-leading techniques found in the Barracuda Spam Firewall that protect against attempts to embed text inside images with the intent of hiding content from traditional spam filters.

Anti-Virus Protection

As virus attacks become more sophisticated and complex, email infrastructure requires advanced virus protection. The potential for the destruction and release of information or the disruption of a network severely impacts productivity and can lead to financial loss.

The Barracuda Essentials for Email Security scans email and incoming files using three powerful layers of polymorphic virus scanning technologies. It also decompresses archives for complete protection. Powerful virus definitions are automatically updated to maintain the most up-to-date protection against email-borne viruses.

Agentless Email Encryption

The Barracuda Essentials for Email Security offers a number of encryption features without requiring complicated key management. It is fully integrated with a cloud-based email encryption service for outbound email. Email that matches policy is securely sent via TLS to the Barracuda Message Center.

The Barracuda Message Center uses AES with 256-bit keys to encrypt emails. To encrypt email traffic between sites over the Internet, the Barracuda Essentials for Email Security supports SMTP over TLS. This can be used between organizations that leverage a Barracuda email security solution or other email servers that support SMTP over TLS.

Outbound Filtering

Outbound filtering prevents organizations from being put on spam block lists and prevents outbound attacks originating from inside the network. Employees can inadvertently cause internal systems to become a source for botnet spam. Using a subset of its defense layers, the Barracuda Essentials for Email Security’s outbound filtering stops outbound spam and viruses.

Data Leak Prevention

Sensitive data abounds in company networks, and it is far too easy to send this information out of the company via email. Data Leak Prevention allows administrators to configure policies that will automatically recognize sensitive content. This content can be as straightforward as credit card numbers and social security numbers which are identified by predefined filters, as well as data that conforms to any number of custom policies. When sensitive information is detected in outbound mail, it can either be blocked or automatically encrypted, again, based on configurable policies.

Email Continuity

The Email Continuity Service ensures that email operations continue by failing over to a cloud-based, email service, in the event primary email services become unavailable. During email server outages, an emergency mailbox allows users to continue sending, receiving, reading, and responding to email.

Denial of Service (DoS) Attack Prevention

Not every attack is focused on planting a virus, or getting users to send their credit card number or to click on a malicious link. Often, the objective of the attack is focused on disabling a network or mitigating its effectiveness. As a cloud-based service, the Barracuda Essentials for Email Security is positioned to stop spammers before they overload an email server.

Archiving, Compliance and eDiscovery

The Barracuda Cloud Archiving Service assists organizations with compliance and eDiscovery requests effectively and easily when used with Microsoft Exchange, Google Apps, and other on-premises, cloud or hybrid environments. It offers productivity features, including mobile applications for end users to search and retrieve email at any time from any device. The Barracuda Cloud Archiving Service creates a cloud-based indexed archive. This allows granular retention policies, extensive search, auditing/permissions, legal hold and export, helping to facilitate compliance retention and eDiscovery preservation. Legal holds preserve email from being tampered with until it?s removed. Native and mobile apps provide intuitive interfaces that ensure messages are found easily. The Barracuda Cloud Archiving Service creates an indexed archive to support extensive search, auditing/permissions, legal hold and export, helping facilitate eDiscovery and retention. These easy-to-use search capabilities, ranging from the most basic search by a user for a misplaced email to advanced Boolean search strategies for an auditor during an eDiscovery request.

Simple Cloud-Based Management

An intuitive web interface makes administering the Barracuda Essentials for Email Security easy and straightforward. With no hardware to install, initial deployment takes less than 30 minutes.

While the default settings are often all that many organizations ever need, the Barracuda Essentials for Email Security has a broad range of settings that can be customized to meet special requirements. For example, some email sources can be whitelisted to bypass filtering, while other sources can be blacklisted for complete blocking. Administrators can customize filters independently for inbound and outbound email to selectively prevent passage of email content that is sensitive in nature or contrary to an organization’s objectives and standards.

Customers that use several Barracuda products (such as Office 365 users running Barracuda Essentials, which combines email security with data protection features)can manage all their Barracuda products from a single interface: the Barracuda Cloud Control (BCC). This web-based management portal leverages Barracuda’s global cloud infrastructure to enable organizations to centrally manage all their Barracuda products through a “single pane of glass” interface. Administrators gain a global view of all their devices or services, as well as centrally manage policies and configuration. The simple interface makes it easy for organizations to implement and manage multiple services with minimal IT overhead.
